Wheat Flour Farine ATM 50 Kg - Biscuit Flour - Bread Flour - All Purpose Premium Wheat Flour Different types of flour contain different amounts of protein. It varies considerably amongst brands and the geographic location where the wheat is grown. Soft wheat flour, sold primarily in the South and cake flour are much better for biscuits and pie crusts. Hard wheat flours, sold primarily in the North and Midwest, are better for breads. There are as many as 30 types of protein in wheat flour available now in our supply, but only two of those are important for our purposes: gliaden and glutenin. When they come in contact with moisture (water, milk, etc.) and are stirred, they produce gluten which gives elasticity, strength and shape to baking recipes.
